| Abstract: | The basic concept, construction principle and implementation for the ADS(Automatic Dependent Surveillance) system are presented. The tracking precision is one of the most important factors of the practicality of ADS system. The outburst disturbance and the lose of ADS message and error code caused by the change of plane' s attitude severely affect the tracking precision of ADS system. An Kalman filtering algorithm based on the "Current" model is adopted to process the ADS data to improve the tracking precision of ADS system. Numerical simulation shows that this method is effective. This Kalman filtering algorithm makes the ADS system more practicable for ATC(Air Traffic Control). |
